In binary computing, 16 bit numbers range from 0 to 65535 (or 1 to 65536). Generating large numbers randomly is a recurring problem in cryptography.

In board games and other tabletop games, dice are referred to as d[number] according to their number of sides. A traditional six-sided die would be a d6. Dice larger than a d20 are rare specialty dice, and are often nicknamed "golf balls" to emphasize how unwieldy they are.

Here, Cueball has somehow constructed a d65536 for generating random 16 bit numbers. It has solved the problem of being secure from a cryptography standpoint, but presents a new set of challenges from its sheer size, dwarfing an average human. While large in itself, a die that big could still be emulated by rolling multiple dice (e.g. 8 4-sided dice or 16 coin flips) and converting the result into binary before getting the desired number.

The closest regular shape similar to the depicted in the comic could be a {{w|Goldberg polyhedron}}. However no such polyhedron exists with exactly 65536 hexagonal faces. The closest Goldberg Polyhedron has a mixture of 65520 hexagons and 12 pentagons, totaling 65532 sides.

The title text references how many cryptographic systems (especially RSA and other factoring-is-hard based systems) are hypothetically vulnerable to quantum attacks if we could build quantum computers large and coherent enough to actually compute on more than a few qubits. The title text is essentially punning on the idea of a "large" quantum system. "Large" in the quantum computing sense would be on the order of 64 qubits each of which would be an atom or two at most. This would still be microscopic and will never be as large as the giant die the comic is centered on.

==Trivia==
If a real d65536 where constructed with each number having an equal area and each printed in 12 point font, the resulting die would be about 5 feet (1.5 meters) in diameter.

[Drawing of a large die with many sides, about ten meters in diameter; Cueball is standing next to it as a size reference. A small portion of the die's surface is zoomed in, showing hexagonal faces with five-digit numbers.]

The hardest part of securely generating random 16-bit numbers is rolling the d65536.
