LET US PAINT JENNIFER'S REGULAR HM(36) There is regular Hadamard matrix with 3×3 cells, order 36, presented at paper (1969). Painting shows the structure this matrix.
If to permutate 2 and 3 rows of blockmatrix, we will have symmetric situated blocks, but non symmetric matrix (structure above is symmetric).
Let us prepare three level Cretan matrix CM(37) by this regular core.
