	CROSSREFS	`See BP977 for a version without infinite nesting and other drawings than boxes.` `Adjacent-numbered pages: BP1066 BP1067 BP1068 BP1069 BP1070 * BP1072 BP1073 BP1074 BP1075 BP1076`

BP1107

Contains smaller copy of self with black and white inverted vs. not so.

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

	COMMENTS	`There are various problematic cases left out. Are black and white to be inverted within a fractal's convex hull or its outermost outline?` `Must this outline be preserved around the smaller inverted version of the fractal, or is it allowed to bleed into other white areas?` `No examples have been included in this Bongard Problem whose placement depends on these questions.`

BP1115

Fractals tile one another vs. not so (fractals are rather tiled by some combination of one another and themselves).

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

	COMMENTS	`Rotations and reflections avoided in all examples for simplicity.`
	CROSSREFS	`Adjacent-numbered pages: BP1110 BP1111 BP1112 BP1113 BP1114 * BP1116 BP1117 BP1118 BP1119 BP1120`

BP1116

Contains self somewhere within any area around any point within self vs. not so.

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

	COMMENTS	`Very similar to the less clearly-defined solution "tiles itself with infinitely many copies (different sizes allowed) vs. does not".` `The left hand side of this is a weaker condition than the left hand side of BP1241.`
	CROSSREFS	`Adjacent-numbered pages: BP1111 BP1112 BP1113 BP1114 BP1115 * BP1117 BP1118 BP1119 BP1120 BP1121`

BP1118

Self-similar only scaled about one point vs. multiple centers of self-similarity.

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

	COMMENTS	`There is only ever one such center of self-similarity or infinitely many.`
