Good starting point. Next, you can multiply byI started off by using 5c1 to choose the one suit that gets a repeat

which is the number of permutations of 6 distinct kinds (some write 13P6). Then divide by

to remove the redundant permutation of two kinds in the same suit.

Finally, to adjust the 6 consecutive kinds, you need to subtract the number of consecutive kinds from

before you do the multiplication.
