## B. Dodecahedron

Time limit: 0.5 second
Memory limit: 64 MB
Vasya has 30 rods of equal lengths. Each rod is painted in some color. He is going to construct a dodecahedron using these rods as its edges. He is interested in how many different dodecahedra he can obtain (Vasya calls two dodecahedra equal if one of them can be obtained from the other by a sequence of rotations).

### Input

30 integers that are colors of the rods. The colors lie in range from 1 to 30. The numbers are delimited with whitespaces.

### Output

Output the number of different dodecahedra Vasya can construct.

### Sample

```1 1 2 2 2 2 2 2 2 2
2 2 2 2 2 2 2 2 2 2
2 2 2 2 2 2 2 2 2 2
```
```11
```

### Notes

Dodecahedron is a regular polyhedron with 20 vertices and 12 pentagonal faces.
