These are the terms that are not formed this way and can be considered primitive terms of A323711. The first term containing the digit 0 is a(15) = 157836042 and the first term containing the digit 9 is a(13) = 137965842. %C A306265 Terms in A323711 without the digits 0 and 9 are in the sequence. %H A306265 Chai Wah Wu, <a href="/A306265/b306265.txt">Table of n, a(n) for n = 1..5845</a> %e A306265 A323711(3) = 1402857. Deleting the digit 0 results in 142857 which is A323711(1). Similarly, deleting 0's and 9' from A323711(3)-A323711(20) results in another term of A323711 and a(3) = A323711(21). %Y A306265 Cf.
