Found it at Sloane's integer sequences: sequence A000543

Thanks.

Hard to "picture" 333...need a couple Tylenols

Thanks Buddy.

My 27 is wrong.

Added information:

If a cube can be obtained by rotating another cube,

these two cubes are NOT considered to be different.

If there was only 2 colors, the answer would be 23.

You have an unlimited supply of black, red and white unit (1x1x1) cubes.

Use any 8 of these cubes to create different 2x2x2 cubes.

What is the maximum number of these cubes that you can create?

Using 200,000 borrowed, over 25 years, rate 6% annual compounded monthly P = Payment (?) A = Amount borrowed (200000) n = number of payments (25 * 12 = 300) i = periodic (monthly) interest rate (.06/12 = .005) Formula: Let v = 1 / (1 + i)^n P = Ai / (1 - v) v = 1 / 1.005^300 = .22396.... P = 200000(...
