How many words can we form?

[Jivago]

How many words using these rules can we get?

we have 26 letters

y is a vowel here : rhythm , syzygy etc ...

w is a vowel too here : wppwrmwste (an obsolete spelling of uppermost)

thus vowels are : a e i o u y w

minimum of letters for a word : 2 ( needs a vowel )

maximum of letters for a word 29 !!!

maximum of consonants in a row : 6 ( but the same can't be repeated consecutively more than twice = sss ttt mmm bbbb etc .. but if interwoven it is ok : archchronicler , schylds , wppwrmwste etc )

maximum of vowels in a row : 5 ( but the same can't be repeated consecutively more than twice = aaa iiii uuuuu etc .. but if interwoven it is ok : queueing etc )

THANKS .. hope someone can help . please show the equations used if possible : )

I don't see why a word cannot have a single letter!

sure ... a word can have 1 letter only too : )

How about words like "I'' and "a"?
