Semiregular honeycomb

Imagine a honeycomb that has a special pattern that makes it not quite regular (meaning it doesn't have perfectly even honeycombs like you normally see). Instead, some of the honeycombs are bigger or smaller than others, but they still fit together nicely like a puzzle. This is called a semiregular honeycomb! It's kind of like if you were building with blocks and some of the blocks were different sizes, but they still fit together perfectly. It's a little bit different, but still really cool!
