It seems to me that the original intent of the thread was to multiply the stated number by each of its digits, in ascending order, and then either state a new number and repeat or repeat the process with the product obtained after all digits have been used. That would have yielded a more interesting sequence too. But since I'm here, 525 duovigintillion 810 unvigintillion 643 vigintillion 939 novemdecillion 383 octodecillion 144 septendecillion 408 sexdecillion 655 quindecillion 691 quattuordecillion 666 tredecillion 896 duodecillion 156 undecillion 911 decillion 912 nonillion 285 octillion 969 septillion 118 sextillion 88 quintillion 134 quadrillion 656 trillion multiplied by 54 is equal to 28393774772726689798067407350012392473243263442332376759271424000000000000 or approximately 28.4 trevigintillion. I hope somebody has checked all these digits and verified all the terms of the sequence lol!

I confirmed the first 15 digits of my own term for this sequence, and the first three digits of a few others. I suppose that is confidence enough. Can anyone show me how to write an explicit formula for a sequence like this?

~28.4 trevigintillion * 55 = 1561657612499967938893707404250681586028379489328280721759928320000000000000 or approximately 1.56 * 10^75 which is about 1.56 quattuorvigintillion.

Wow, that seems rather obvious now. Thank you very much!

123 * 56! = 87452826299998204578047614638038168817589251402383720418555985920000000000000 ~ 8.75 * 10^76 ~ 87.5 quattuorvigintillion

The posts were absolutely correct, incidentally.
