CF 103379E - Grandest Wreath

Vertices are binary strings $a{2t-1}ldots a1a0$ with exactly $t$ ones. A move consists of choosing $j in {1,ldots,2t-1}$ and swapping $a0 leftrightarrow aj$. Each move preserves the condition $sum{i=0}^{2t-1} ai = t$, hence maps $(t,t)$-combinations to $(t,t)$-combinations.
