A109924 is defined as a(n)="Least palindromic multiple of concatenation 123...n"
with the comment "Leading zeros are allowed (but are not shown)".
An example of suppressed leading zeros is
a(10) = 12345678910*10971041 = 135444,949494,445310
But by the same rule shouldn't we have
a(2) = 12*5 = 60 not 12*21 = 252
a(5) = 12345*3034 = 37,454730 not 12345*43483 = 536,797635
a(6) = 123456*37315 = 4606,760640 not 123456*50061 = 6180,330816
