Sorting out First Forward pages:
https://nrich.maths.org/7963 New First Forward hub. Needs text.
Moved navigation links in First Forward articles to top of page, and linked to home at bottom of page.
Pages (in the series) checked and fixed: 1567, 1564, 1561, 1566, 1559, 1568 (required drastic changes: I've re-named it since the title refers to duplicate content from FF12)
Replacing First Forward links everywhere to new hub (used to link to FF1).

Notes:
Someone needs to give descriptions to all the things that are just "imported legacy object".
The transposition and substitution challenge is really tricky and requires a great degree of luck and intuition. 3 star?
