Arapacana Alphabet in the Pañcaviṃśatisāhasrikā prajñāpāramitā in Sanskrit and Chinese

A comparative table of Arapacana Alphabets in the Pañcaviṃśatisāhasrikā Prajñāpāramitā Sūtra in Conze's English Translation; the new Sanskrit edition by Takayasu; Kumārajīva's 404 CE Chinese translation (Taisho 223); and Xuán Zàng's 663 CE Chinese translation which collates a number of PP sūtras (Taisho 220).

There's quite broad agreement up to about letter 26. Note that Conze also uses the Chinese translation by Mokṣa of Khotan (Taisho 221), but so far I haven't identified the arapacana alphabet in this text. All the lists except Conze include repetitions. Conze's solutions to this problem look likely and involve Prakrit spellings of Sanksrit words, i.e. ṣaṃga for saṅga at no.10. (Note that the Chinese transliterations support this sustitution by using an aspirated sibilant sound.) The number of syllables in the various alphabets various from 41-43 (Dutt has 44!) but we know that later in the Pañcaviṃśati the text is expecting 42 (dvācatvāriṃśad akṣarāṇi PSP_6-8:67-8).
