A130399 : correction

[zak seidov]

Sequence ends with 30:
(and Eric's terms after 29 aint OK?!)

1,3,4,5,6,7,8,9,11,13,15,17,19,22,23,24,25,26,27,28,29,30

No term after 30, as any number m>30 shares last digit
with m-30.

Consider all such sequences A_n (including also the finite ones).
The sequence B: B(x) = min { A_n(x) for all n } *is* uniquely defined,
and might be of slightly more interest (though considering the 'base'
nature, probably only marginally so).
