Summary[edit]

Description

The 256 fixed points in Zhegalkin permutation Ж4 (row 4 of Sloane's A197819), which has length 65536

The columns of the 16×256 matrix are the fixed points.
The rows are Walsh functions, i.e. XORs like (which is in row 3).
The 16×8 matrix on the left indicates the arguments in the XOR (and the row number in this Walsh matrix).
Its upper half shows a Sierpiński triangle without the main diagonal, and the lower half shows the main diagonal.
(Hence the lower half of the 16×256 matrix is identical to the gray index matrix on top.)
