Any recommended stack that seems like shuffled and random but card locations can be work out through mathematical formula??

Thank you.

I use a mem deck now, but I've always been partial to Si Stebbins, although I know some fear it is too easily noticeable for certain tricks (such as where multiple cards in a sequence are called out or revealed).

I guess one question would be if you are wanting to determine the position of a card in the deck once it is named via a mathematical formula (e.g. someone names a card and you tell them it is in position 23), or you just want to be able to determine the cards above or below a known card in the stack? If it's the former, I still suggest Si Stebbins as it looks reasonably mixed at a glance and is easy to calculate. You may want to look into Si Stebbins Pro, which eliminates the alternating color sequence and still allows for the calculation at any position. Another worth checking out is the Bart Harding stack.

If it's the latter, and you only need to be able to discern what card comes next, a popular mathematical stack that definitely looks random, but allows you to work out the subsequent card in the stack, is Osterlind's BCS.

That's a few options to get you started. Smile

A few are mentioned in my essay on full-deck stacks.

Thank you sgtgrey! The former purpose is exactly what I what: determine the position of a card in the deck once it is named

Which mentioned stack in your opinion,Si Stebbins Pro or Bart Harding, allow a quicker (less steps) mental calculation for the performer to location the position of named card??

Honestly, I couldn't tell you as although I've read about the stacks, I've not put in the time to use them since I now work with a memorized deck, which is instantaneous. I guess one question would be why you're choosing a mathematical stack and using calculations vs memorizing a stack? Although it's more work up front, memorizing an order is going to be much faster in performance, not to mention easier (since you've done the "heavy lifting" beforehand) - and contrary to popular belief, memorizing a deck isn't all that much work - especially not with today's technology and books on memory systems.

Not exactly what youre asking for but Doug Dyments Quickerstack is a beast. As is all his material.

If youre willing to sacrifice immediate access to a particularly useful property in Dougs setup its possible to hybridize Quickerstack with Michael Webers Card Kindergarten. Besides memorizing a somewhat significant amount of cards the majority of the stack becomes a one to one translation. Its also super fun to play with as the cards are ordered so consistently that certain gambits encompass the majority of cards.



As for other stacks Stebbins is coming into vogue again as people play with Hackerstack, Redfords Stack and Quickerstack. In addition there should be some material published soon(?) that makes Stebbins even more tantalizing.

I would like to second JB's comment above. Quickerstack is tremendous. Explore his site referenced above. It contains a wealth of information and materials.
