Commentary
The affix कप् does not come after a बहुव्रीहि समास the last member of which ends in the affix ईयस्।
This debars all the previous rules. Thus बहवः श्रेयांसोऽस्य = बहुश्रेयान्, here rule 5.4.154 is debarred. बह्व्यः श्रेयस्योऽस्य = बहुश्रेयसी, here rule 5.4.153 is prohibited. By rule 1.2.48 the long final ई ought to have been shortened, but this is not done by considering it as a masculine "ईयसो बहुव्रीहौ पुंवत्" See Vartika under 1.2.48.
