+Each instance of the dataset consists of two integer partitions of \\(20\\) (one 
+corresponding to the irreducible
+representation and one corresponding to the conjugacy class) and the
 corresponding character (which is always an integer). For a small \\(n = 5\\) example, 
 if the first partition is `[3,1,1]`, the second partition is `[2,2,1]`, and the character
 is `-2`, then this says that the character \\(\chi^{3,1,1}_{2,2,1} = −2\\).
