 \begin{proof}\leanok
     First use Theorem~\ref{thm:periodic_equalcase_matching} to match the
-    periodic bases. For each matched block, apply
+    bases of periodic tensors. For each matched block, apply
     Theorem~\ref{thm:equalcase_zgauge_power_sums} to the singleton list of
     multiplicity entries.
