 OFFSET 1,1 COMMENTS Some pattern is visible which would change when numbers of three or more digits occur in A082249. Conjecture: If the concatenation of k consecutive r-digit numbers is divisible by n then the concatenation of the next k numbers would also be divisible by n provided it contains the same number of digits as the first number. This should be true for both forward and reverse concatenation. LINKS Table of n, a(n) for n=1..13. CROSSREFS Cf. A082242, A082243, A082247, A082248, A082249.
