One unclued light (ignore its umlaut) is the home of a team known by a name which is another unclued light. This name is also given to a group of 13 28; four related members (one hyphened) are the other unclued lights. Each of ten clues contains a misprinted letter in the definition part; corrections of misprints spell a two-word description of the team’s game, accounting for the absence of one of the best-known 13 28 from the grid.
