(In reply to computer findings--unambiguously
75 is definitely the correct answer for the dot-marked dice, where no ambiguity exists regarding the interpretation of the number of dots.
On the other hand whoever got ,say 1;3;5 and two sixes(NORMAL DIGITS) and wrote down 13566, could arrange the dice as
13569 or 13599 and still comply with the 3 conditions mentioned in the problem.
Therefore the correct answer for the case of the ambiguous dice is significantly higher than twice 75 and I leave it to you to provide it , if you are so inclined.
Clearly, your new list will start with 56699 and terminate by 11226.
Significantly bigger challenge is solving the problem with P&P.
Everybody is welcome.
