what is the 3rd pl perf ind mp Attic of φαίνω?

My apologies for this apparently stupid question; must be a glitch in my mind–looked every place I could think of.

πέφανται ?

φαίνω
entry in LSJ
πέφανται verb 3rd sg perf ind mp
πέφανται verb 3rd pl perf ind mp epic ionic

I believe that would be πέφανται…

What about

πεφασμένοι εἰσίν ?

Bedwere is right. It’s the periphrastic form.

Smyth secs. 599e; 707:

599
e. In the third plural of the perfect and pluperfect middle (passive) the perfect middle participle with εἰσί (ἦσαν) is used when a stem ending in a consonant would come in direct contact with the endings -νται, -ντο. See 408.



707. Indicative.—The perfect middle is inflected by adding the primary middle endings directly to the tense-stem, herein agreeing with the μι-conjugation. The pluperfect adds the secondary middle endings. In vowel verbs the formation is simple, as in λέλυ-μαι, ἐλελύ-μην. But in consonant verbs, the consonant at the end of the stem comes into collision with the consonant at the beginning of the ending; hence certain euphonic changes described in 409. The periphrastic form occurs in the 3 pl. and sometimes in the 3 sing. (599 d, e).

a. Stems in ν avoid the forms -ν-σαι, -ν-σο; thus, from φαίνω, instead of πέφανσαι, ἐπέφανσο the periphrastic πεφασμένος εἶ, ἦσθα were probably used.

–I.e., the same as singular? Even in Attic?

Hylander–Thanks a lot! Very helpful.
