Wikipedia:Articles for deletion/Sparse representation of a number
Sparse representations of bitvectors are definitely important, and there has even been some interesting research on algorithmic problems of arithmetic with sparse binary numbers (those with few 1's in their binary representation; see Plaisted, "New NP-hard and NP-complete polynomial and integer divisibility problems", FOCS 1977). That said, this article doesn't touch on any of that, its references are useless for establishing notability of this topic (they're on something peripheral to it), and to the extent that what it says is non-obvious it appears to be original research. So, per , if this were to be turned into a usable article it would need to be completely rewritten, and there's no point in keeping the present version while we wait for that to happen
