Assuming a password can be of any length from 1 to 12; for each length L there are 37 possible characters at each position, so 37^L possible choices. The total is SUM(37^L, L=1..12) = SUM(37^L, L=0..12) - 1 = (37^13-1) / (37-1) - 1 = 6765 81178 37800 36260 Lynn Yarbrough | |||||

In that case the number is simply 37^12, or 6582 95200 58400 35281. | |||||
