Dear Tzungkuen,

t> When I read the section of Sobhanacittam in
t> "Abhidhammatthasangaho", I find it used
t> 'catuviisali' and 'catuviisati' for the same meaning '24'. But in
t> PED Dictionary I can only find viisati meaning 20. Is viisali also
t> equal to viisati?

Probably this is a misprint. I have not found such word as 'viisali'
or 'catuviisali' on Chattha Sangayana CD.

With metta,
Dimitry
