Subject identification numbers in a certain scientific research project consist of five digits followed by four letters and
then three more digits. Assume repetitions are not allowed within any of the three groups, but digits in the first group
of five may occur also in the last group of three. How many distinct identification numbers are possible?
chosen from the letters A to Z
26PA
Evaluate 26P4
26!
26P4=
(26 -4)!
