Here’s the example they give:

It works for me!

]]>def check(a, b): # check combinations below 120 N = 120 c = [0] * N for n in range(0, int(N / a) + 1): for m in range(0, int((N - a*n) / b) + 1): s = a*n + b*m if not(s < N): continue c[s] += 1 if not(c[59] == 1): return if c[:60].count(0) < 2: return if len([x for x in c[:60] if x > 1]) < 2: return if len([x for x in c[60:] if x > 1]) < N - 60: return print(a, b, c[:60], c[60:]) # OK, let's assume a < b for b in range(3, 60): for a in range(2, b): check(a, b)

**Edit:** Yes, this is the edited post. The [sourcecode] tags are successfully maintained. (In fact the post editor seems to be somewhat better than the comment editor).

I have posted about this problem at the WordPress Support Forums.

Here is some Python code that is a solution to **Enigma 1646**.

from fractions import Fraction from collections import Counter ms = Counter() for x in range(15, 255, 15): for y in range(0, 195, 15): ms[Fraction(y - 80, x)] += 1 print(len([m for m in ms.values() if m > 1]))

The problem is when presented in the editor the line:

`[sourcecode language="python"]`

is presented as:

`[sourcecode language=""python""]`

Notice that the double quotes around `python`, become duplicated. Unless this is resolved manually before saving the comment, it will be messed up when displayed.

I will now reproduce the code in a comment, and then edit it and add one additional line at the end.
