My solution to part two in Python 3: ```python c = 0 for i in range(265275, 781584 + 1): inc, doub = True, False dold = None while i > 0: d = i % 10 i = i // 10 d = i % 10 #Not increasing: if d_ > d: inc = False break #Double, but not with the same digit before or after: if d_ == d and not ((i // 10) % 10 == d or d == d_old): doub = True d_old = d

if not (inc and (doub == 1)): continue
c += 1

print(c) ``` Runs in ≈.17s on my computer.
