Following the path of the sequence S recently presented by Eric Angelini ,

“Smallest integer not yet present in S such that the sum of the a(n) first
digits of S is a prime”,

I have computed, by hand, some terms of a similar one:



 « Smallest integer not yet present in S such that the sum of the first a(n)
terms of S is a prime »



2,1,4,6,3,7,8,10,11,15,12,18,14,16,22,24,19,31,28,20,23,37,36,30,26,34,29,35,42,38,40,32,39,45,52,44,54,46,56,60,43,51,50,64….



Can anyone check and extend it? Thanks.



Paolo
