I am writing something for which Nishant sir wil kill me [3]

Polya's Enumeration Formula for the cube is:

1/24 * (c6 + 3*c4 + 12*c3 + 8*c2)

where c is the number of colors

hey injun i think we cant take the qn as an anology of a dice.becos here all the faces are identical,but in a dice all are distinct.

injun joe ·

But we make them distinct by numbering them in different order!!
We can surely do so by painting them!

@ Nishant bhaiyya

if there are two colors only say 1 and 2
we can use color 1 on one face and color 2 for rest five
and...... vice versa ... all other positionings in which one of the colours is used for only one face should be identical [7]
