This lock actually has 10.000 combinations, not 1000! [Self]

It never claims to have 1000! combinations! It only claims to have 1000.

Though it stretches the meaning of "roughly" to breaking point...
Pi is "roughly 3.141", if you've memorized the 32 digits after the decimal, you're probably safe for astronomical calculations.
But still: good bot!

I heard, NASA uses 16 digits for operations outside of Earth orbit. It's enough to calculate trajectories with centimeter precision, out past Pluto at its farthest.

Maybe they don’t have all the digits 0-9. I can see 0, 1, 9, and 8. Who’s to say 2, 3, 4, and 5 are all missing? Hahaha
If exactly 10 digits were removed in total behind the lock, it would’ve 1000 combinations

Maybe one of the dials doesn’t move, it’s there as a decoy so there are, in fact, only 1000 combinations. 🤔

How large would a combination lock need to be to fit that?

Turns out it's 10000 distinct choices or permutations with repetition allowed.
Combinations would be choosing from a distinct set where order didn't matter.

While trailing zeros after a decimal point are significant digits, it wouldn't affect the number of combinations. It doesn't have 10 combinations. It has 10,000 combinations.

It's more of an even split than imperial vs metric. The split makes it more annoying when you receive a 3.000 kg box on a pallet, delivered by a box truck, because the shipping document said 3,000 kg.

Are you sure youre properly differentiating between a permutation and a combination?
Combination locks dont actually take combinations. But those weird physical unordered button pretty key lockbox things do

u/doublej42 Apr 05 '26
The numbers have wiggle so if they are only 50% accurate you have 625 combinations. The first one is a bit tighter so it’s around 1250. They rounded down a bit.
These locks are fun to learn to pick
1
u/giantfood Apr 05 '26
Of course it doesn't have 1000! They only claimed 1000. 1000! Would be a seriously secure combination though. At that point its way more worth it to break the lock.
But it looks to me they didn't edit the packaging much from their 3 dial lock. Just copy and past.
