Why it matters
Dunand listed 114 signs, Martin regrouped them into 27 palaeographic classes, Garbini counted about 90 by merging variants, Vita and Zamora put the figure at no fewer than 100, and the GEAS transcription works with about 100 graphemes; the two tablets alone use 74[1][2][3][4][5]. The size points to a syllabary of open syllables with some logograms, and a phonetisation statistic suggests roughly a third of the signs are logographic[5].
