COMMENT

If m is in the sequence then all numbers of the form g(m,s,t) for non-nagative integers s and t are in the sequence (the function g has been defined in the sequence A101704), for example g(3267,1,1)= 326703267 is in the sequence. If n=0 or n>1 then 33*(10^n-1) is in the sequence.

EXAMPLE

g(3267,10,2) = 32670000000000326700000000003267 is in the sequence

because reversal(32670000000000326700000000003267) =

76230000000000762300000000007623 =

(7/3)*32670000000000326700000000003267, g(3267,0,4) =

32673267326732673267 is in the sequence because

reversal(32673267326732673267) = 76237623762376237623 =

(7/3)*32673267326732673267.
