Just had another thought on "time to completion" as an attribute when synthesizing oscillators. Sometimes, especially for low period oscillators, it's helpful for the synthesis of the active region to be "slow" and the synthesis of the stabilizing objects to be "fast", because otherwise the active r...

The smallest period with no syntheses in http://catagolue.hatsya.com/census/b3s23/synthesis-costs is 65. Most of the initial "oscillator revolution" was done before the p13 domino sparker was found. It can be combined with a toaster or middleweight volcano to create a p65 LCM. Can this be synthesiz...

The last two steps seem to shift a Block inductor back to its original position, or am I missing something? I added those last two steps to get the block in the other location, but also the reverse direction in case that other form ever gets a much cheaper synthesis such that it would make the firs...
