This is output from a program I am working on. Currently, it creates a random field and finds the number of each pentomino within. I want to use the pentomino counter to find answers to questions like, "What is the minimal 2-succinct cover of the pentominoes?" See my polyomino cover site if you care to know what that means. No, that's not terminology you'll find anywhere else. If there are real terms better than the ones I made up, I'd like to know.
