Tetrapent Pair Oddities
is a figure with binary symmetry formed by an odd number of copies of
Oddities can also be constructed from two different shapes.
Here are the minimal known oddities for pairs of tetrapents,
using at least one copy of each tetrapent.
Please write if you find a smaller solution or solve an unsolved case.
See also Tetrapent Oddities
and Tetrapent Triplet Oddities.
Each of these tetrapents has three cells pointing in the same direction.
