Abstract:
In [1], C. Ashbacher, studied the Smarandache reverse sequence: 1, 21, 321, 4321, 54321,
654321, 7654321, 87654321, 987654321, 10987654321, 1110987654321,(1) and he
checked the first 35 elements and no prime were found. I will study sequence (1), from
different point of view than C. Ashbacher. The importance of this sequence is to consider the place value of digits for example the number 1110987654321, to be considered with its digits like this: 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, and so on.(This consideration
