or रु?
Look at it: ) then [रु]? No, it looks like रु or ऋ or कृ with a stroke through it?
Wait, look at the footnote/brackets. It looks like a character was struck through, or is it ङ्घ्रितुङ्गकम्?
Wait, look at तुङ्गकम्: तु ङ्ग क म् - wait, there is an ा? ङ्गा? No, तुङ्गकम्.
Wait, what is that character right before ङ्घ्रि?
Wait! Let's re-read line 15:
अष्टहस्तावसानं स्याच्चतुर्थांश(द्वादशाम)ङ्घ्रितुङ्गकम् ।
Wait, what is the word?
"चतुर्थांशं द्विरष्टांशं" or "द्वादशांशं"?
Ah! In Manasara:
"चतुर्थांशं द्वादशांशं वा..." or similar!
Wait, द्वादशांशं! Look inside the parentheses:
द्वा द श ा शं?
Wait, look at श: then ा, then श or म?
Wait, look at the character before ङ्घ्रि: it has a vertical line, a horizontal strike-through? No
