A079708

Metaprime binary to standard binary conversion series.

0, 1, 2, 3, 6, 12, 20, 28, 140, 260, 64, 11, 30, 420, 7488, 1922800, 11285855256250575, 54979022626732989863421863670075405480 (list; graph; refs; listen; history; text; internal format)

	OFFSET	`0,3`
	COMMENTS	`Each term in the series is computed by translating the previous term to binary, then re-interpreting the binary expression as a product of metaprimes. Metaprimes follow the form p^(2^n) where p is a prime number and n is a nonnegative integer. See the link for more detailed explanation.`

	FORMULA	`a(0)=0, a(n)=A052330(a(n-1)). - Tomasz Ordowski, Jun 20 2005`
	EXAMPLE	`20 (decimal) = 10100 (binary) 10100 (metaprime binary) = 7 * 1 * 4 * 1 * 1 = 28 (decimal)`
