Inflation

Inflation is the process of replacing each cell in a pattern, live or dead, with a larger m×n rectangle of cells in the same state.

Inflation of a 4×4 soup to 8×8.

Inflation can be thought of as taking the Kronecker product of, in order, a given pattern and an m×n matrix of ones.

Uses

apgsearch 4.x and above (apgluxe) support inflation of soups of arbitrary (pseudo-)symmetry by a factor of 2ⁿ×2ⁿ by prefixing the i operator to the desired symmetry string n times.
