Of the three-digit integers greater than $500$, how many have two digits that are equal to each other and the remaining digit different from the other two
2 zeros : 4
1 zero : 5*2=10
the rest have no zeros
2 of 1,2,3,4 : 4*5 = 20
2 of 5,6,7,8,9 and one 1,2,3 or 4 : 5*4*2=40
2 of 5,6,7,8,9 and one 5,6,7,8,9 : 5*4*3=60
4+10+20+40+60 = 134
