This function seems to have been defined at http://mrob.com/pub/math/largenum-7.html and not discussed in any formally published sources since. I think it's WP:MADEUP and WP:OR. —Kodiologist (t) 18:46, 4 July 2016 (UTC)

- Delete - I agree with the nominator that it is probably made up (but I have seen that before where it turned out to be wrong) but for sure it lacks the sources required to meet the notability guideline. DeVerm (talk) 19:23, 4 July 2016 (UTC)
- Delete: This function was certainly not made up by the creator of the mrob.com page, which is trying to describe the construction of Rayo's number to readers with relatively little mathematical background. And the FOST(x) function given there precisely corresponds to the definition of Rayo's number when the value of x is a googol. I would in fact be suggesting a redirect if I thought that FOST was a standard name for this function - however, there is absolutely no evidence of this and, in fact, I suspect that the source of the mrob.com page, lacking an established name for the function, was simply using an acronym for first-order set theory as a temporarily convenient way of referring to it.
