Bit Pattern Shape Visualiser

Explore 4-bit families such as ?0?0 and ?1?1, remove the primes, and see which surviving numbers form shapes on the 0–1–2 grid using the mapping 00 → 0, 01 → 1, 10 → 2.

0 matches
0 survivors
0 outside grid

Bit pairs are read as ab|cd and plotted as (ab, cd) on the 0–1–2 grid when both pairs are one of 00, 01, or 10.

Pattern
?0?0
Surviving decimals
0, 8, 10
Grid points
(0,0), (2,0), (2,2)
Shape reading
Right triangle / L-shape

This tool removes primes from the matched 4-bit family, then maps the remaining numbers to the 0–1–2 grid. Values containing 11 in either 2-bit half lie outside the strict 0–1–2 grid and are listed separately.
