BP799

Position-independent Bongard Problems where positioning varies vs. position-independent Bongard Problems where positioning is consistent

(edit; present; nest [left/right]; search; history)

	COMMENTS	`All examples in this Problem are position-independent Bongard Problems.` `Positioning here includes objects' positions within the panels and objects' positions relative to each other.` `There are very subtle distinctions to be made between the usage of variance of position in these BPs for the sake of noise (obscuring the solution eg. BP557), clarity (generalising the solution to make it more fundamental eg. BP79) or help (aiding the observer in finding the solution eg. BP334). There is certainly a degree of overlap between these three definitions, they are not disconnected.`
