"Recevoir" is an irregular -ir verb that's shortened in all forms, given a vowel change from 'e' to 'oi' in the 'je,' 'tu,' 'il/elle,' and 'ils/elles' forms, and given a spelling change on the letter 'c' in those same forms.

There are four types of changes in French present verb conjugations: the change in length, with singular forms usually being shorter than the plural forms, the change in letters, with the "je," "tu," "il/elle," and "ils/elles" forms being slightly different from the "nous" and "vous" forms, spelling changes, where the conjugation changes due to the nature of French verbs, and any other irregular change that doesn't fit in the first three categories.

The reason why the 'ils/elles' form of 'venir' is 'viennent' instead of 'vienent' is because in French, you can't have a stressed /ə/ sound before a consonant and a mute e, so it has to accommodate by changing the /ə/ to an /ε/, this time by doubling the letter 'n.' 'Viens' and 'vient' don't have this change because -s and -t are both consonants, but the 'ils/elles' suffix -ent begins with a vowel, changing the 'vien-' from a closed syllable to an open syllable.
