	OFFSET	`1,1`
	COMMENT	`Observe in the sequence that although the values of 2^g-1 are often maximal marginal connected numbers, this is not an absolute rule.`
	EXAMPLE	`Between 1024 and 2048 (i.e. in the range with binary order 11) 1139 and 2047 are the smallest and largest composite connected numbers.`
	CROSSREFS	`Cf. A029827, A036277, A036280-A036290.` `Sequence in context: A040211 A003891 A022349 this_sequence A070920 A056484 A056474` `Adjacent sequences: A036376 A036377 A036378 this_sequence A036380 A036381 A036382`
