Hello SeqFans, A remeven number is a positive integer such that when divided successively by all its digits the remainder is always even: S = 1,2,3,4,5,6,7,8,9,11,12,14,15,16,18,22,24,26,28,32,... (no zero digit allowed in n, of course) The remodd numbers, like 73, are less common, I guess. Best, É. É. Catapulté de mon aPhone
