#N comparison-2.rle
#O Various; arrangement by Connor Steppie
#C
#C This is a comparison of two "MarBlocks" oscillator families
#C listed next to each other for behavioural comparison.
#C This pattern is identical to the previous file, but two rule
#C transitions have been changed to modify the behaviour of these
#C oscillators: now the cores will remain solid instead of instantly
#C dying out when they fill in. Note how the periods for each line
#C remain exactly the same despite this change, as the edge
#C behaviour is identical here.
#C
#C A system for naming MarBlocks rules was proposed in 2018 by
#C conwaylife.com forums member 77topaz, with help from Dave
#C Greene, which would classify each rule using an octal system.
#C The rule emulated by this pattern would therefore be "M11",
#C and the previous example would be rule "M10".
#C
#C Open this pattern with showinviewer.lua to see labels which
#C indicate the period of each of these oscillators. They can be
#C seen to follow Sloane's A085587 (linked below).
