A230452 Starting values for which the "comma sum" sequence (cf. A230288) does not end in 989. 3

%I #6 Oct 19 2013 10:16:48

%S 0,1,2,3,4,47,49,52,54,59,64,65,67,69,70,72,74,75,76,77,80,81,82,86,

%T 87,88,89,91,92,93,94,396,398,401,403,405,406,409,410,411,414,416,417,

%U 421,422,426,428,431,433,435,436,439,440,441,444,446,447

%N Starting values for which the "comma sum" sequence (cf. A230288) does not end in 989.

%C According to the general rules, the starting value 0 ends in 1, therefore the value 0 has been included here. However, we list it with index 0 since the original sequence A230288 had been *defined* to start 0,5,11... (and ends in 989), so some might consider that 0 should not be here.

%C This sequence obviously includes all integers beyond 989.

%o (PARI) for(n=0,999,vecmax(A230288_vec([n],150))==989||print1(n","))

%Y Cf. A230288, A230450, A230453.

%K nonn,base

%O 0,3
