NonZeroRadicalsOfProjectivesOfProjectiveAndInjectiveDimensionAtMostOne on DyckPath ​

The nonzero radicals of the indecomposable projective modules whose projective and injective dimensions are both at most one.

On DyckPath

FindStat's St001241. The radical of the projective at vertex v starts at v + 1.
