Patterned Wristband

A wristband can have 4 patterns:

1. horizontal: each item in a row is identical.
2. vertical: each item in each column is identical.
3. diagonal left: each item is identical to the one on it's upper left or bottom right.
4. diagonal right: each item is identical to the one on it's upper right or bottom left.

You are shown an incomplete section of a wristband.

Write a function that returns True if the section can be correctly classified into one of the 4 types, and False otherwise.
