Flushed With Embarrassment

[JHostler]

Colm Mulcahy's latest bit of mathemagic. I've taken an interest in this one for obvious reasons:

Colm's Latest

Oddly, this only works [for me] when I alter the critical cut to "...between two adjacent cards neither of which are on lists B or D" rather than "...neither of which are on lists A or C."

This is great -- thank you Colm and John.

Richard: delete this thread immediately, it's too good.

[Chris Aguilar]

Very interesting concept.

Thanks, Bob!

Forgot to mention: I believe Fulves messed with Gilbreathean principles in the context of poker deals... maybe as early as Riffle Shuffle Set-Ups(?) In any case, I really like what Colm has done w/ TDQ.

FYI - Those of us interested in mathemagical principles/concepts have something new to look forward to. Mulcahy's 378-page "Mathematical Card Magic" is apparently due on 9/4/13: http://www.amazon.com/Mathematical-Card ... lm+mulcahy

[JHostler]

Unbelievable - it's here, on schedule. See above link(!)

I'm counting the days using a combination of binary numbers and the Gilbreath principle.

Thanks for reading this far. I am currently DC-based.

Apoloogies, it seems that promo offer expired as soon as book was actually released. I didn't know.

Jack Shalom has discovered something very cool... a previously unpublished attribute of the Triskadequadra principle that greatly simplifies its application and may open new doors. As this is his discovery, he owns the revelation... but I've got every finger and toe crossed that he shares it in some form.

Paging Colm Mulcahy…

OK... Jack has granted permission to release this. Those familiar with the principle will understand:

There is no need to check post-shuffle to see whether you've obtained family #1 or family #2. Just monitor the pre-shuffle cut: If the suit of the bottom card of the top packet matches the top card of the deck, you are in the family that has doubles of cards #2 and #4. Otherwise, the doubles will be of cards #1 and #3.

For example, with a deck in CHSD order (top to bottom, face-down): If the bottom of the top packet is a spade, your shuffle generates family #1: CHSD, CCHD, SSHD. If the bottom of the top packet is a club, you get family #2: CHSD, HHCS, DDCS.

Unfreakinbelievable.
