The image is the infinity symbol. It looks like a horizontal number eight. The lines are doubled like the image was traced over but there is space between the lines. Nothing is touching the figure.
This Infinite icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,700 icons, all in the same style and quality.
