Hello Math-Fun, One can produce an integer by concatenating the digits spelling a full date -- example for today, May 2nd, 2007: --> 20070502 This 8-digit integer can be represented like this: abcdefgh. I was wondering if there exist a (close) date fulfilling this: abcdefgh = h*g*f*e*d*c*b*a where as many * as one wishes can be deleted. (but not all of them! -- concatenate accordingly to produce a sound set of factors. For instance: abcdefgh = hgfe*d*c*b*a or abcdefgh = h*g*f*edcba or abcdefgh = hg*f*e*d*c*b*a ... Best, É. (I think the "direct" equality is impossible: abcdefgh = a*b*c*d*e*f*g*h)
