I've seen several different naming schemes used for pentominoes. This is
- the system I'm using (I think only F & N require a bit of imagination)
- FF I L N PP TTT U U V V W W W X X Y ZZ
FF I L NN PP T UUU V V W W X YY Z
F I L N P T V X X Y ZZ
I LL N Y
A 3x20 solution (the other solution is easily obtained by a rotation of
- the section from the Z to the L inclusive)
- UUXPPPZYYYYWTFNNNVVV UXXXPPZZZYWWTFFFNNLV UUXIIIIIZWWTTTFLLLLV
- A 4x15 solution
- IIIIINNLLLLTVVV UUXNNNFZZWLTTTV UXXXYFFFZWWTPPV UUXYYYYFZZWWPPP
2 5x6 rectangles. Joined side-to-side, end-to-end, or stacked, these
- enable construction of the 6x10 & 5x12 rectangles, and the 2x5x6 prism
- NFVVV YYYYI NFFFV LLYZI NNFXV LZZZI PNXXX LZWTI PPUXU LWWTI PPUUU WWTTT
The 2x3x10 and 3x4x5 solutions are tricky to show - I hope these diagrams make sense:
A 2x3x10 solution (shown as 2 layers; Y and L are shared between the
- 2 layers)
- VVVZIIIIIF UUXTTTWWPP VZZZNNNFFF UXXXTWWPPP VZYYYYNNFL UUXYTWLLLL
- A 3x4x5 solution (3 layers, V F W & L shared between 2 or more layers)
- VUUXF VZFFF VNYFW VUXXX TZZZW NNYPW VUUXW TTTZW NYYPP IIIII TLLLL NLYPP
