KIRKMANOV PROBLEM O UĈENICAMA
                                        KIRKMAN'S SCHOOLGIRL PROBLEM

    Uĉenik : NIKOLINA MARKOVIĆ I razred Gimnazija u Lazarevcu
    Mentor : VESNA RAJŠIĆ, profesor matematike Elektrotehniĉka škola „Nikola Tesla”

                                                         REZIME

    Kirkmanov problem o uĉenicama intezivno je izuĉavan u 19. veku, ali uglavnom kao problem rekreativne

    matematike. Ovaj problem  i  njemu sliĉni  koji pripadaju  oblasti kombinatorike zvanoj  blok  šeme  ili  blok

    dizajn,  imaju  direktnu  interpretaciju  u  blok  dizajnu.  One  su  blisko  povezane  sa  razliĉitim  nauĉnim
    disciplinama                     kao                      što                                         su:

    statistika - kada je reĉ o organizaciji eksperimenata, elektrotehnika-pri konstrukciji kodova koji ispravljaju
    greške,                        projektivna                         geometrija,                        itd.

    Za  rešavanje  ovog  i  niza  drugih  zanimljivih,  praktiĉnih  problema  postoje  odreĊeni  prirodni  zahtevi  o

    pravilnom  rasporedu  u  konaĉnim  skupovima.  Rešenje  Kirkmanovog  problema  vodi  do  takozvanog
    Štajnerovog     sistema     trojki,    nazvanih     tako     prema     radovima      Jakoba      Štajnera.

    U ovom radu ćemo se baviti pronalaţenjem zanimljivih rešenja za Kirkmanov problem i njegovom vezom sa
    blok šemama i Štajnerovim sistemom trojki.


    Kljuĉne reĉi : skup, taĉka, podskup, blok šeme, Štajnerov sistem trojki.


                                                        SUMMARY

                                                                        th
    Kirkman’s  schoolgirl  problem  was  intensively  studied  in  the  19   century,  mainly  as  a  problem  of
    recreational mathematics. This problem and similar, which belong to the field of combinatory called block

    shemes or block design, have the direct interpretation in the block schemes. They are closely associated with
    a            variety           of           scientific          disciplines,           such           as:

    statistics – regarding the organization of the experiments, electrical engineering  – the construction of the

    error        –        correcting        codes,         the        projective        geometry,         etc.
    For solving this and many other interesting, practical problem, there are certain natural requirements on a

    regular schedule in final sets. The solution of Kirkman’s schoolgirl problem leads to the so – called Steiner

    triple         system,         by          the          works          of          Jacob          Steiner.
    In  this  study,  we  will  deal  with  finding  the  interesting  solutions  for  the  Kirkman’s  problem  and  its

    connection with the block schemes and Steiner triple system.

    Key words: set, point, subset, block schemes, Steiner triples system.
