A Puzzle - Algorithm Needed or Involved?

[wemack88]

I am trying to solve a puzzle. How do I find an algorithm (or a formula) behind a series of six two-digit numbers? (The numbers are as follows: 14, 21, 33, 41, 56, 68.) The two-digit numbers, although different from one another, are always the same ones given. Each time they are rearranged differently. I have been given 45 instances of these six two-digit numbers. I need to calculate the next sequence, the forty-sixth.

Is there a formula (an algorithm) to determine the answer?
Any help warmly received.

lots of algorithms you could attempt to use to solve this...
The two problems this puzzle might be that come to mind are
[0] the sequence maybe a permutation generator.
[1] something to do with modulus.
