The answer is **1 in 72193**.

This calculation is actually much simpler than the odds of a
triple, and it's actually simple enough to easily do without a
calculator. A straight flush can begin at 1 (ace) up to 9 (since we
don't want to include the royal flush which starts at 10),
therefore there are **9** possible straight flushes for each
suit, and there are **4** suits. Therefore, the total number of
straight flushes is 9*4=**36**. Therefore, we can divide the
total number of combinations (2598960) by 36 to get the odds of a
straight flush: 1 in 72193.
