T(1,1) = 0, which is first number in which the number of distinct base 10 digits is 1. That row has only one other element, 1. T(2,2) = 12, which is first number not beginning with a zero in which the number of distinct base 10 digits is 2. The row begins: 10, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 23,.... 0,1,2,3,4,5,6,... 10,12,13,14,15,16,17,... 102,103,104,105,106,107,108,... 1023,1024,1025,1026,1027,1028,1029,... 10234,10235,10236,10237,10238,10239,10243,... 102345,102346,102347,102348,102349,102354,102356,... 1023456,1023457,1023458,1023459,1023465,1023467,1023468,...
