 A259344 Array read by antidiagonals: number of inequivalent m X n (0,1)-matrices under permutation of rows and permutation and/or complementation of columns. 0
 1, 1, 2, 1, 3, 2, 1, 4, 4, 3, 1, 5, 7, 8, 3, 1, 6, 11, 19, 10, 4, 1, 7, 16, 41, 32, 16, 4, 1, 8, 23, 81, 101, 68, 20, 5 (list; table; graph; refs; listen; history; text; internal format)

Harrison, On the number of classes of binary matrices, IEEE Transactions on Computers, C-22.12 (1973), 1048-1052. (Annotated scanned copy) EXAMPLE The first few antidiagonals are: 1, 1,2, 1,3,2, 1,4,4,3, 1,5,7,8,3, 1,6,11,19,10,4, 1,7,16,41,32,16,4, 1,8,23,81,101,68,20,5, ... CROSSREFS For some rows, columns, diagonals see A006380, A006281, A006382, A006383. The second row of the array starts 2,4,7,11,16,23, which does not identify it uniquely.
