Building upon earlier work of Donna Carr, Don Pelletier, Chris Johnson, Shu‐Guo Zhang and others, we show that a normal ideal J on P κ ( λ ) is strongly normal if and only if J + →< ( J + , μ ) 2 for every μ < κ , and we describe the least normal ideal J on P κ ( λ ) such that J + →< ( J + , κ ) 2 .
