1 2 without 7: 8× 8× c (4, 1) = 4× 8? ;

Two sevens without two are: 8× 8× c (4,2) = 6× 8? ;

Two twos without seven are: 6×8? ;

1 2， 1 7: 8×8×A(4，2)= 12×8？ ;

Three 7s without 2 are: 8× c (4 4,3) = 4× 8; 3 2 without 7: 4× 8;

7:8×c(4, 1 )× c (3,2) =12× 8 of two 2,1; Two 7,12 are:12× 8;

There are four 7: c (4,4) =1; 2 of 4 has1;

So * * * has: 4×8? ×2+6×8? ×2+ 12×8? +4×8×2+ 12×8×2+ 1×2=5890
