Five Fives Game

[maasman]

I'm fine with more functions. The main reason why I dislike the ceiling/floor functions is that you can abuse them to essentially get any number you want out of a single 5 by just using repeated square rooting and random other functions.

Also, I can't figure out 373 without using the ceiling/floor functions.

[crispybits]

I got 373 without ceiling/floor already:

373 = (5!! + .5) x Γ5 + 5/5
373 = 15.5 x 24 + 1
373 = 372 + 1
373 = 373

Next target = 379

So what's the new rule? we can use any function except floor/ceiling?

[crispybits]

I think we've always been able to use any function, just now I've made a list of them that's as complete as I can find infor for - we still can use floor/ceiling but maasman and I are avoiding them if possible.

[maasman]

379 = (5+5!!/5)!! - √5 x √5
379 = (5+3)!! - 5
379 = 384 - 5
379 = 379

[crispybits]

383 = σ(5!) + 5! + 5!! + 5 + Π5
383 = 240 + 120 + 15 + 5 + 3
383 = 383

(having done all that bloomin research I've gotta slip some of the "new" ones in there )

[maasman]

Because I'm lazy:

389 = (5+5!!/5)!! + √5 x √5
389 = (5+3)!! + 5
389 = 384 + 5
389 = 389

[crispybits]

397 = Γ5 x (5!! + (Π5 x .5)) + μ(5!!)
397 = 24 x (15 + (3 x .5)) + 1
397 = 24 x 16.5 + 1
397 = 396 + 1
397 = 397

[maasman]

401 = 5# x 5!! - 5 x 5 - Γ5
401 = 30 x 15 - 25 - 24
401 = 450 - 49
401 = 401

[crispybits]

409 = Γ5 x (5!! + σ(5!!)) + 5/5
409 = 24 x (15 + 2) + 1
409 = 24 x 17 + 1
409 = 408 + 1
409 = 409

[maasman]

419 = 5# x 5!! - 5# - 5/5
419 = 30 x 15 - 30 - 1
419 = 450 - 31
419 = 419

[crispybits]

Too easy to cheat this one

421 = 5# x 5!! - 5# + 5/5
421 = 30 x 15 - 30 + 1
421 = 450 - 29
421 = 421

Next target: 431

[maasman]

431 = 5# x 5!! - 5!! - σ(5!!)) - σ(5!!))
431 = 30 x 15 - 15 - 2 - 2
431 = 450 - 19
431 = 431

[crispybits]

433 = (5# - σ(5!!)) x 5!! + 5!! - σ(5!!)
433 = (30-2) x 15 + 15 - 2
433 = 28 x 15 + 13
433 = 420 + 13
433 = 433

[maasman]

439 = 5# x 5!! - 5!! + σ(5!!)) + σ(5!!))
439 = 30 x 15 - 15 + 2 + 2
439 = 450 - 11
439 = 439

[crispybits]

443 = Γ5 x (Γ5 - 5) - (5!! - σ(5!!))
443 = 24 x (24 - 5) - (15 - 2)
443 = 24 x 19 - 13
443 = 456 - 13
443 = 443

[maasman]

449 = 5# x 5!! + (√5 x √5)/5
449 = 30 x 15 - 5/5
449 = 450 - 1
449 = 449

[crispybits]

457 = Γ5 x (Γ5 - 5) + 5/5
457 = 24 x (24 - 5) + 1
457 = 24 x 19 + 1
457 = 456 + 1
457 = 457

[maasman]

Still lazy.

461 = 5# x 5!! + 5!! - σ(5!!)) - σ(5!!))
461 = 30 x 15 + 15 - 2 - 2
461 = 450 + 11
461 = 461

[crispybits]

Same here

463 = Γ5 x (Γ5 - 5) + 5 + σ(5!!)
463 = 24 x (24 - 5) + 5 + 2
463 = 24 x 19 + 7
463 = 456 + 7
463 = 463

[crispybits]

Are you stuck on the next one maasman or you just taking a breather?

[maasman]

Just breather.

467 = 5# x 5!! + 5!! + φ(5) - σ(5!!))
467 = 30 x 15 + 15 + 4 - 2
467 = 450 + 17
467 = 467

[crispybits]

479 = (5# + σ(5!!)) x 5!! - 5/5
479 = (30 + 2) x 15 - 1
479 = 32 x 15 - 1
479 = 480 - 1
479 = 479

[maasman]

487 = 5# x 5!! + Γ5 + 5!! - σ(5!!))
487 = 30 x 15 + 24 + 15 - 2
487 = 450 + 37
487 = 487

[crispybits]

Another cheat

491 = 5# x 5!! + Γ5 + 5!! + σ(5!!)
491 = 30 x 15 + 24 + 15 + 2
491 = 450 + 41
491 = 491
