Summary[edit]

Description
Image set Zhegalkin indices drawn to linear patterns
The white and red rows of the upper matrix form an 8×256 matrix,

whose columns represent natural numbers. (Compare the upper matrix in this file.)

This matrix of height 8 is drawn to height 16, by introducing empty rows, which are highlighted in gray.
The non-empty rows form a linear Boolean function, i.e. a 4-ary Walsh function (see here) or its negation.

The columns of the lower matrix are the Zhegalkin twins of those above.

The rows of both matrices are 8-ary Walsh functions (see here).
Their indices are shown in the small matrices on the left. (Compare small matrix on the left of this file.)

Metadata

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.
