Use the complete finite self-map on Fin(5)={0,…,4} given by T(x)=(a*x+b) mod 5, a=1, b=-7. Choose the least nonnegative residue, including for negative a*x+b. Time is discrete, indexed from 0; a finite orbit is not a general stability result. x0=0, updates=0. Give (modulus, a, b, x0, update count, orbit including x0). Zero updates gives the one-element prefix [x0].
G001 — Use the complete finite self-map on Fin(5)={0,…,4} given by T(x)=(a*x+b) mod 5, a=1, b=-7. Choose the least nonnegative residue, including for negative a*x+b. Time is discrete, indexed from 0; a finite orbit is not a general stability result. x0=0, updates=0. Give (modulus, a, b, x0, update count, orbit including x0). Zero updates gives the one-element prefix [x0].Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
Before
X={0 through 4}; T(x)=(1x+(-7)) mod 5After
remainder representative always lies in X
Conditions: none
Fix the full finite state carrier and the same update rule;negative integers also use the standard remainder from0 through n−1.
Rule: finite_total_map · Uses: G001
Before
x₀=0; transitions=0
After
initial orbit prefix=[0]
Conditions: none
Retain the initial state;steps=0 still has one known state,not an empty list.
Rule: orbit_initial_state · Uses: G001, S001
Before
computed transitions=0
After
orbit=[0]; number of entries=1
Conditions: none
Apply the same T to the preceding result; k transitions give k+1 states.
Rule: orbit_prefix_length · Uses: G001, S002
Before
a finite requested prefix
After
no unrequested least-period claim
Conditions: none
This output is the requested prefix;it is not an unverified least-period proof from a few orbit values.
Rule: finite_prefix_scope · Uses: G001, S003
S004 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.S003 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.S002 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.(5, 1, -7, 0, 0, [0])
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
