Not Subset Of

The 'not-subset-of' icon represents a mathematical symbol used to indicate that one set is not a subset of another. This icon is often used in educational materials and digital platforms to convey relationships between sets and their elements.

In educational software and online resources, this icon may appear in contexts where mathematical concepts are being explained or illustrated. For example, it could be used to demonstrate set theory and logical relationships.

From a user experience perspective, the 'not-subset-of' icon communicates complex mathematical concepts in a clear and concise manner. It helps users understand the relationships between different sets and their properties.

Not Subset Of is one of 9,161 icons in Phosphor, made by Phosphor Icons and released under MIT. It is drawn on a 256 × 256 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds NotSubsetOfIcon to components/icons/ph-not-subset-of.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed NotSubsetOfIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Yes, if your project has @phosphor-icons/react: Not Subset Of is `NotSubsetOf` there, used as <NotSubsetOf />. The shadcn.io MCP server answers with that import when it finds the package. Without it, copy the icon from here.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Not Subset Of icon, or any of 9,161 Phosphor icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 256 × 256 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Not Subset Of", so screen readers say what it does.

Yes. NotSubsetOfIcon passes every SVG prop to the svg element, so <NotSubsetOfIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes. MIT allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: MIT only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Phosphor, Phosphor Icons and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.

Its tags are math, logic, comparison, set and theory. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Not Subset Of in another set.

Phosphor draws many icons in several styles: Bold, Light, Thin, Duotone and Fill next to the default. Open the library and pick a style above the grid to see Not Subset Of's siblings in it.
