Prime factorization:

1782 = √4 * (√!4)4 * L(√!4)!

Could not find better than:
1783 = (τ(4!!) + ((√!4)!)! + (4!!)!!) / ((√!4)!)!!

1784 = ((!4)! + (4!!)! + F4!) / τ(√!4)

Spoiler:
1783 = τ(24) / 11!! - !6

1786 = (T(4!) + T(4!!) * τ((√!4)!)) / T(L(√!4)!) = (T(4!) + √4) / (!4 * L!4)

Nice

1787 = ((!4)!! * F(T(√!4)!) - (4!!)!!) / L(L(√!4)!)

### Re: Count Up with the Four Fours Puzzle

Thanks. Too many possibilities:

1788 = (τ(L(√!4)!) + τ(L(√!4)!) / T(T(√!4)!)) / L(T(√!4)!)
1788 = (F(L4!!) - (4!!)! - F(L(√!4)!)) / !((√!4)!)
1788 = (L!4 * !(4!!) - T(F4!!)) / L(T(√!4)!)
1788 = T(√!4)! * τ(L(√!4)!) / (!(4!!) - F(F4!!))

1789 = Ack(√!4, 4!!) - 44

Spoiler:
1789 = Ack(√4, Ack(√4, Ack(√4, Ack(√4, Ack(√4, Ack(√4, Ack(√4, Ack(√4, √4 + √4))))))))

Very nice! I completely forgot about the Ackermann function.

1790 = (τ(4!) + (!4)!) / τ(√!4) / ((√!4)!)!!

Feeling lazy.

Very nice! I always forget to check squares...

Edit: forgot one 4

Thanks! I built a part specifically to look for them so will be doing a couple more.

Speaking of which...

1815 = τ(4!!) * L(√!4)!!! * T4!! / τ(4!)
1815 = √((T(√!4)!!! + τ(4!!)) * (√!4)! / .4)
1815 = √(T(T(√!4)!) - (τ(!4) + T!4) * L4!!)
