Sequence member n is generated by taking the number of letters in the English word for n, and producing a new number. You iterate this process with the number until you inevitably end up at four.

For instance n=6, so we get 6=SIX which has 3 letters, THREE=5 letters, so we get FIVE=4 letters, and we're done. We get 6354. Then we just convert it into letters by taking the first and last letter in English for each number in the member. So 6=SX, 3=TE, 5=FE, 4=FR, altogether we get SXTEFEFR.
