This entry occurs after alpha 17 in ms A (= Parisinus 2625), after alpha 9 in ms S (= Vaticanus 1296) and in the margin of ms D (Bodleianus Auct. V 52).
[1] The given form is a dative plural of a)/bac, ("abacus"), and the lexicographer explains it by reference to the diminutive a)ba/kion. The primary sense is a table topped by a slab, or the slab itself; a "calculator" is a secondary meaning.
[2] Symeon Metaphrastes (also known as the Logothete ('Lawmaker')) Patrologia Graeca 115.837c. On Thecla, cf. tau 1108.

Same entry in Photius and elsewhere. The headword, masculine/feminine accusative singular or neuter nominative/singular of this two-termination adjective, must be quoted from somewhere; extant possibilities are all late.
Besides the literal meaning there is also an applied one, in Pythagorean mathematical literature: an odd number; see LSJ s.v. at web address 1 below.

Same or similar entry in Photius and other lexica, and cf. also the scholia to Apollonius Rhodius, Argonautica 3.1323.
See already under alpha 825.
Dimensions in akainai are especially common in the technical treatises of Hero [Author, Myth](n), but see also e.g. Diodorus Siculus 20.91.4 (as conventionally restored) for square akainai.

Same entry in ps.-Zonaras; similar ones in Photius (s.v. a)napempa/zesqai) and Hesychius (s.v. a)napempa/zei and a)napempazo/menoi, on the second of which see below).
[1] The Aeolic form for pe/nte "five" is pe/mpe -- both from Indo-European *penkwe.
[2] This actual form of the present middle participle, the nominative masculine plural, occurs in (and might therefore be quoted here from) Lucian, Menippus 12. Note however that Photius s.v. cites Plato in this context, i.e. accusative a)napempazome/nous in Plato, Laws 724B.

See already alpha 2827 (and cf. alpha 2825, alpha 2826).
[1] Alexander of Aphrodisias, Commentaries on Aristotle's Topica 547.21-22. In the Posterior Analytics Aristotle speaks of two types of indemonstrable propositions: (1) the axioms, i.e. those principles that a learner must already have if he or she is willing to learn any scientific discipline (An.Post. 72a17; see also Metaphysics 1005a20. These indemonstrable axioms include the general laws of thought, such as the principle of non-contradiction and the law of the excluded middle; see An.Post. 71a13-14; Met. 1005b19-20). (2) What Aristotle understands as the peculiar principles of a scientific discipline, i.e. some items that are proper to each particular science. For instance, arithmetic assumes the existence of units, geometry that of points and lines (An.Post. 76a37-76b5).
