Before /san, the /abhyAsa a अ becomes i इ.

pac पच् + /san + /laT → !**pipakSati पिपक्षति "wants to cook"

yaj यज् + /san + /laT → yiyakSati यियक्षति "wants to sacrifice"

sthA स्था + /san → **tiSThAsa- तिष्ठासॱ

Because of sanvallaghun... 14>, this rule does not apply just before /san, but also to some /Ni roots before /caG —

kam कम् + /Ni + /luG
→ **acIkamata अचीकमत

(here the i इ got lengthened by dIrgholaghoH 15>.)

Why do we say "before /san"?

No i इ substitution before, say, /laT or /liT —

hA हा + /laT /tip → **jahAti जहाति

pac पच् + /liT /tip → **papAca पपाच

Why do we say "the abhyasa a अ"?

u उ is unaffected —

yudh युध् + /san + /laT → !**yuyutsate युयुत्सते "wants to fight"

Why do we say "after SHORT a अ"?

Long A आ appears in the desiderative of the intensive pApacyate पापच्यते, and it stays unchanged —

pApaciSate पापचिषते "wants to cook a lot"
